I found these old 1968 GCSE [then called O’ level] Maths papers in my study. Try them and see what you think.
1968 O Level Maths Paper 1 * 1968 O Level Maths Paper 2
And these are 1962 Ordinary Level Maths papers – passed to me by my dear friend, Frank.
1962 O Level Maths Paper 1 * 1962 O Level Maths Paper 2
And Graham’s 1957 Ordinary Level Maths Papers
